foot prints and ammonites mainly, but any kind of organism if it had any contact with mud, under the right condition, it might just becomes a fossil
Full
mold
A fossil I pressume. . . Well the leaf is buried in some gloopy mud, and the mud drys around it making a cast / impression. The leaf rots a away after this because it is so fragile. The mud is lithified and bingo an impression. Am I barking up the right tree. . .
A fossil of this type is called an impression fossil. It forms when an organism's body creates an imprint in soft mud or sediment, which then hardens into rock and preserves the shape of the organism but not its actual remains. These fossils provide important information about ancient organisms and their environments.
A mold fossil is formed when an organism decays and leaves an impression in the surrounding sediment or rock. Over time, the impression fills with minerals, creating a cast of the organism's shape.
A cast fossil is formed when an organism dies and leaves an impression in sediment. Over time, this impression can fill with minerals, creating a replica of the organism's shape. The original organism then decays or is washed away, leaving behind the cast fossil.
Sometimes a fossil is formed when the organic matter is impressed in clay or some similar substance. The organic substance rots away, but the impression it left remains, and if the clay which holds the impression petrifies, it becomes a fossil.
Yes.
This is called a trace fossil. or a mold.
A fossil created by a print or impression is called an imprint fossil. Imprint fossils are formed when an organism's remains leave an impression in sediment that hardens over time. This process captures the shape or texture of the organism, providing valuable information about ancient life forms.
They are an example of a trace fossil
It is a fossil.
